Because they aren’t accountable - after it is merged only I am. And why would I want to go back and forth with an LLM through PR comments when I could just talk to the agent myself in real time? Anytime I want to work through a pile of slop I can ask for one, but I don’t work that way. I work with the agent to create plans first and refine them, and the author of a PR who couldn’t do that adds nothing.
